It relates to an apparatus and a method for producing a chlorine dioxide water removal.

Chlorine dioxide (ClO ₂ ) is a powerful oxidizing agent that oxidizes toxic chemicals such as almost all bacteria, viruses, molds (anthrax), etc., but it is a material that is safe for the human body when used in an appropriate concentration (WHO safety highest standard A-1 grade).

In addition, chlorine dioxide is not only 5 times higher in oxidizing power and 10 times higher in water solubility than chlorine oxidizing agents, which are widely used in the past, and does not produce chloramine, which is known as a toxic ingredient, so it is the latest beverage manufacturing process and food product in developed countries. It is widely attracting attention as an alternative oxidizing agent for chlorine in various industrial fields ranging from sterilization and disinfection in processing and storage processes, water purification plants, and organic matter and odor removal processes in wastewater treatment plants.

In particular, chlorine dioxide does not generate carcinogenic disinfection by-products such as THMs, HAAs, HANs, etc., which are emerging as the biggest problem of chlorine-based oxidizing agents, as well as a wide and high level against various kinds of microorganisms, bacteria, and viruses in a wide pH range. It has the advantage of having sterilization and is the only material that can remove the resistant bacteria of chlorine-based disinfectants and the biofilm, a hotbed of bacteria.

In addition, chlorine dioxide, which is both an oxidizing agent and a sterilant, has a strong sterilization power that completely removes various viruses and protozoa, compared to conventional oxidizing sterilants such as chlorine, ozone, bromine chloride, and chloramine, and oxidizes heavy metals such as iron and manganese. It also has a function to precipitate into oxides and hydroxides.

The chlorine dioxide injection device capable of selectively injecting gases, solutions, and bubbles described in Patent Publication No. 1977036 (announced on May 10, 2019) filed by the applicant of the present invention uses a pump in manufacturing chlorine dioxide. Thus, a configuration is shown in which sodium chlorite and an acid solution must be supplied and air is supplied to the chlorine dioxide reactor using an air pump.

In addition, the portable constant concentration pure chlorine dioxide gas generator described in Patent Publication No. 1736825 (announcement on May 17, 2017) is used to manufacture chlorine dioxide by attaching an air control valve to a dropping means, sodium chlorite storage tank and acid storage tank. The composition is shown.

In addition, the apparatus for producing chlorine dioxide described in Japanese Unexamined Patent Publication No. 2011-508718 (published on March 17, 2011, Patent Document 3) uses a tank-type first to third raw material supply unit and an inert gas supply unit to produce chlorine dioxide. The configuration to be manufactured is shown.

In addition, the high-yield pure chlorine dioxide production apparatus described in Patent Publication No. 1901260 (announced on September 28, 2018) filed by the applicant of the present invention produces chlorine dioxide using a low concentration sodium chlorite solution and a sulfuric acid solution. However, a configuration for producing chlorine dioxide using a first air pump and a second air pump is still shown.

However, the above inventions still have a tank-type raw material storage unit to install the main body of the chlorine dioxide production device, use a pressurizing device such as a pump, or require a separate air injection device, and the device is too large and complicated. There was a problem that it was done.

At this time, by initially opening the on-off valve 413 and opening the first water shut-off solenoid valve 411, the second water shut-off solenoid valve 431 is shut off, so that water along the water supply pipe 410 It is supplied to the aspirator 420, and since the gas supply pipe 310 is connected to one side of the aspirator 420, the gas filtration tank 300 communicating with the gas supply pipe 310 is depressurized, and the gas filtration tank ( 300) and the reaction tank 200 communicated by the gas discharge pipe 220 is depressurized.

In addition, in the present invention, in order to smoothly maintain the decompression state of the reaction tank 200 or to control the concentration of the chlorine dioxide solution, the second water shutoff solenoid valve 431 initially shut off is opened or shut off after a certain period of time. You can adjust the water supply by doing.

When the reaction tank depressurization step is maintained as described above, the reaction tank maintains a constant decompression state, and air is continuously sucked from the outside.

[1st and 2nd raw material supply step: 3rd step]

Step 3 is a step of supplying the first and second raw materials of the present invention to the reaction tank 200, and after the second step, the first and second raw material supply pipes connected to the first and second raw material storage tanks 110 and 120 ( The first and second solenoid valves 113 and 123 are opened as well as opening the valves of the supply/cutting valve 112 of the 111 and 121, and thus stored in the first and second raw material storage tanks 110 and 120. The first and second raw materials are supplied to the reaction tank 200.

At this time, the first and second raw material storage tanks 110 and 120 are installed on the upper side of the reaction tank 200 and the reaction tank 200 is depressurized by the depressurization of the decompression unit 400, so that the first and second raw materials are Even without a separate power source such as a pressure pump, it is naturally supplied to the reaction tank 200.

However, when the apparatus of the present invention is driven for the first time, the amount of water calculated relative to the internal structure and area of the reaction tank 200 is put before supplying the raw materials stored in the first and second raw material storage tanks 110 and 120. In this way, the risk of explosion can be prevented by reacting the first and second raw materials in water.

[Chlorine dioxide gas generation step: 4 steps]

Step 4 is a step of generating chlorine dioxide gas in earnest in the reaction tank 200, and is a step in which the first and second raw materials and air are mixed to generate chlorine dioxide gas.

When the inside of the reaction tank 200 is depressurized in the second step, air is introduced from the inside of the reaction tank 200 through the air inlet pipe 210 communicating with the outside, so that the first and second raw materials are naturally in the reaction tank 200. As the and air are mixed, chlorine dioxide gas is generated smoothly.

As described above, the generated chlorine dioxide gas is discharged to the gas filtration tank 300 through the gas discharge pipe 220. At this time, a moisture removal filter 221 is installed at the inlet side of the gas discharge pipe 220 to discharge chlorine dioxide gas to the gas filtration tank 300 while firstly removing moisture, sodium chlorite and acid.

In addition, as described above, if the water flow of the water supply pipe 410 for depressurization is not detected, the apparatus of the present invention does not operate. Therefore, when the water supply is stopped, the apparatus of the present invention is turned off. The solenoid valves 113 and 123 are also closed. Therefore, when the supply of water is stopped, the supply of raw materials is always stopped, and the risk of explosion due to oversupply of raw materials is also removed.

[Pure chlorine dioxide gas generation step: 5 steps]

Step 5 is to remove the remaining trace amounts of sodium chlorite and acid even after first removing the moisture, sodium chlorite, and acid by the moisture removal filter 221 installed at the inlet of the gas discharge pipe 220 of the reaction tank 200. It reacts secondarily to generate chlorine dioxide gas, removes remaining sodium chlorite and acid, and generates and discharges only pure chlorine dioxide gas.

In order to convert the chlorine dioxide gas generated inside the reaction tank 200 into pure chlorine dioxide gas by step 4, the chlorine dioxide gas flowing into the gas filtration tank 300 through the gas discharge pipe 220 of the reaction tank 200 is filtered. Passing through the unit 320, a trace amount of sodium chlorite and acid discharged together with the chlorine dioxide gas generated in the reaction tank are also reacted secondarily to generate chlorine dioxide gas, and sodium chlorite and acid remaining in the moisture are removed. Is done.

To this end, it is necessary to extend the end of the gas discharge pipe 220 in communication with the reaction tank 200 to the lower side of the filter unit 320 of the gas filtration tank 300, and a gas supply pipe in communication with the depressurization unit 400 The end of 310 is installed above the filter unit 320.

[Steps for preparing chlorine dioxide solution: Step 6]

Step 6 is a step of preparing aqueous chlorine dioxide, in which pure chlorine dioxide gas is mixed with water.

The chlorine dioxide gas generated inside the reaction tank 200 by the above 4 steps is transferred to the gas filtering tank 300 through the gas discharge pipe 220. In addition, while passing through the filter unit 320 of the gas filtration tank 300 in step 5, the pure chlorine dioxide gas from which sodium chlorite and acid have been removed is passed through the gas supply pipe 310 through the aspirator of the decompression unit 400 ( 420, the supplied pure chlorine dioxide gas is mixed with water supplied from the water supply pipe 410 from the aspirator 420, and is supplied to the chlorine dioxide water supply pipe 432 to produce chlorine dioxide water.

The present invention continuously manufactures and supplies aqueous chlorine dioxide by going through the steps 1 to 6 as described above.

In addition, in the present invention, the device is stopped by stopping the supply of water to the water supply pipe 410, specifically by closing the on-off valve 413 or the first water shut-off solenoid valve 411, water flow Is stopped, and the water flow detection sensor 412 detects that the water flow is stopped and turns off the device.
